Good, adding new cards would become easy but i really like the pci_ids.h
approach as is a centralized db, it doesn't take much time to update
the driver to work with my card.

I can't set my fbdev to anything different than the booted mode 640x480-8@60,
trying anything else brings me a black screen or unsynched monitor,
i am using Jon's merged driver (benh+khronos) so probably is not your driver's
fault (but edid support is very tempting, although is not used because i'm
working now on an old monitor without ddc :), i will try your driver alone and
report back.
